Issue regarding FB Like and Send buttons

Howdy All -

Having a CSS issue with a new site we are putting together and thought I would post my question here (after banging my head against the wall for a few hours).

You can view one of our new trip pages at testsite.symg.com/trips/backpacking/john_muir_trail.php If you click on the ‘Like’ or ‘Send’ FB buttons on any of the trip pages, the FB pop up window does not load correctly .The FB help page mentions this issue (see below)

From FaceBook's help page:
================
When I click the Like button, the comment popup window ('flyout') doesn't show. Why?
If the Like button is placed near the edge of an HTML element with the CSS overflow property set to hidden, the flyout may be clipped or completely hidden when the button is clicked. This can be remedied by setting the overflow property to a value other than hidden, such as visible, scroll, or auto.

I have been playing around with this, but can't seem to fix it. I can paste in the full CSS below if that helps, looks like I can't link to it directly.
